HENRY W. MERRITT, OF SYRACUSE, NEW Y ORK, ASSIGN'ORlTO THE MONAROHTYPEWRITER COMPANY, OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK.

TYPE-WRITING MACHINE.

Specification of Letters Patent.

Application filed February 10, 1906. Serial No. 245,078.

To all whom. it may concern:

Be it known that I, HENRY W. MERRITT,

citizen of the United States, and'resident of Syracuse, in the county ofOnondaga and State of New York, have invented certain new and usefulImprovements in Type-.- Writing Machines, of which the following is aspecification.

My-invention relates more particularly to 10' the ribbon mechanism ofthatclass of typewriting machines. commonly called visible writers andwherein the Writing is visible to the operator'as he writes. In suchIna--- chines it is usual toemploy in connection with the ribbon aribbon vibrator or carrier, which term, as used herein, means any devicefor moving the ribbon to and from the printing point under the controlof the printing keys.

One object of my invention. is to provide a construction wherein aribbon having a plu- I rality of fields. of different characteristics 5may at each printing operation. be moved to cover the printing pointwith any of its fields, as desired. v

Another object is'to provide means for dispensing at will with thecrosswise feed of the ribbon in that el-ass of machines employingaribbon vibrator and wherein the ribbon has both. a crosswise and alengthwise feed.

Another object 18 to provide means to enable a ribbon of more than onecolor, com- Y monly called a polychrome ribbon, to be em- Q plo'yecl 1nthe last named classof machines.

.hereinafter more fully described and articularly pointed out in theconclu 'ng claims.

I have illustrated my invention as embodied in the Monarch typewritingmachine, but I desire it to be understood that it may be adapted toother formsof writing machines. I

In the drawings, lindicates the base of a typewriting machine supportingcorner posts 2, which latter sustain a top plate 3.

Key levers 4., each provided with a restoring spring 5, are fulcrumed ona fulcrum plate '6. A sub-lever 7 is pivoted at 8 to each key lever andthe lower portion of said sublever is adapted" to cooperate with a fixedabutment9. The upper end of each sublever is connected .by a link 10-with atype bar 11 which is'one of a segmentally war- 1 ranged series,eachtype bar whereof is seated in a radial slot 12 formedin a segmentahtype bar support 13. The heel of eaoh'type bar-is perforated to permit.of the a groove in the top of the segmental type bar support. The typebars instead of being pivoted on a fulcrum wire, as herein shown,

may each bepr'ovided with individual hangers andpivots. A type rest15.normallysupports the type bars at their free [ends and said bars whensuitably actuated coiiprate with a platen 16 mounted in a carriage 1.7,said carriage beingguided and suppo tedby anti-friction balls '18 whichare seatedein grooved rails 19 .on the carriage and in -op-, positelygrooved rails 20 securedtebrackets 21 fixed to the top plate ofthe machne The carriage .17 is provided with a feed rack 22' which normallymeshes with a "pinion -23, the latter being operativel-y'oonnecteagwithan escapement wheel 24.

. Passage of a segmental -p1vot wire 14 contained .lIl.

extending arm 29 of a universal bar frame.

30 pivoted in the base of the machine at 31. The frame 30 carries auniversal bar 32 which extends from side to side of the ma chine beneaththe series of key levers 4.and the spacing levers (not shown) and-isadapted to be actuated by said levers when the latter are depressedduring printing or spac-- ing operations. The carriage 17 is connectedby a strap orband 33 with a spring drum 34, which constantly tends todraw the carriage to the left, the result being that when the universalbar 32 is actuated, the escapement mechanism above described is causedto be operated in a known manner and thereby to permit of letter spacemovements of the carriage. I

A pair of ribbon spools 35, arranged above the top plate and forwardlyof the platen, one at each side of the machine, receive a ribbon 36which, as herein shown, is divided longitudinally into fields a and b ofdifferent characteristics; for example, the field d may be of one coloras black, and the field b may be of another and different color, as red,or the field a may be copying ribbon and the field Z) record ribbon. Theribbon 36 may be fed lengthwise from either spool to the other by anysuitable means. The drawings illustrate a ribbon feed mechanism which issimilar to that employed in the Monarch typewriting machine, and whichis explained in the United States patent to Jacob Felbel and CarlGabrielson, No.

703,339, dated June 24th, 1902. Each ribbon spool 35 is carried by anupright shaft 37 which rotates in a fixed bearin 38 and has secured toits lower end a smal beveled gear 39. The gear 39 meshes with a beveledpinion 40 secured to the forward end ofa horizontal shaft 41 which shafthas its bearings in lugs 42 and 43 depending from the under side of thetop plate. The shaft 41 carries at its rear end a beveled pinion 44which isadapted to mesh with a beveled from dri ving pinions 45 on thedriving shaft 46. As explained in the above cited patent, the driving orpower shaft 46 is capable of longitudinal movement and the longitudinalposition of said shaft determines which driving pinion 45 will be inmesh with its co-- operating pinion 44 and which ribbon spool will beturned to wind the ribbon thereon.

Midway between the ribbon spools 35 the ribbon 36 is threaded through aribbon cri- .brator or carrier 50 which is supported and ided in theupright arms 51 of a supportmg bracket 52 secured by screws 53 to thetop plate of the machine. The lower portion of the vibrator or carrier50 is bifurcated and carries a cross-pin 54 which is embraced by theslotted forward end of an operating lever fulcrumed at 56 in a lug 57depending from the top plate. arm of the operating lever has formed init an elongated slot 58 which receives a pin or stud 59 secured at thetop of a ver- -tically' arranged link 60. The link 60 is made forconvenience in. several parts which screw into one another or areotherwise suit ably secured together, and the upper part 61 of said linkis flattened and, besides carrying the stud 59, is provided witha'downwardly and forwardly bent'arm' 62 (Fig. 3). At its lower. end thelink 60 is pivoted at 63 to the arm 29 of the universal bar frame. Thelink 60 isadapted to be swung about the pivot 63 in order to cause thestud 59 to move longitudinally of the slot 58 so that said link mayengage the operating lever 55 The rear at varying distances from itsfulcrum 56 and thereby vary the throw of the ribbon carrier or vibrator50. The means employed to swing the link 60 about its pivot 63'andlongitudinally of the lever 55 comprises an eccentric controller ormember designated as a whole by the numeral 64, which member is slidablymounted upon the driving shaft 46 and is adapted to cotiperate withthestrap formed near the top of the link 60.by the part 61 and its bentarm 62. The eccentric member 64 comprises an eccentric working face 65,a tapered or cam portion 66 and a sleeve portion 67, which latter isformed with a circumferential groove or depression 68. A screw 69 passesinto the sleeve portion 67 of the. eccentric member 64 and enters anelongated slot or groove 70 in the driving shaft 46. The eccentricmember 64 is thereby slidably connected with the driving or power shaft46 and is caused to rotate by and with said shaft but may bemovedlongitudinally of. said shaft without,- affecting the latter. The shaft46-inay also be moved. endwise without affecting the member 64. Pivotedforwardly of the linkGO to the arm 29 of the universal bar frame at 7-1is a two-part link 72, the upper portion of which is bentor off-set at 73 and 74 so that the flattened top part 7 5 of said link stands to theleft and forwardly of the top of the link 60, and so that a stud 76secured to said flattened ortion 75 is adapted to engage with the sot 58of the operating lever at the left side of the latter and forwardly ofthe some:

stud 59 which engages-with the slot 58 at the right side of theoperating lever. For most work the stud 76 stands normally out ofengagement with the slotted operating lever 55. Thelinks 60 and 72 arecapable of a slight movement transversely of the 7 operating lever 55so. as to provide for the alternate engagement. of the studs 59 and 76of said links with the slot 58 in the oper ating lever. Ahorizontallydisposed spiral 1 spring 77, having, one'end secured to the connectingrod28 and the other end to the link 60, tends to constantly swing thelatter .rearwardly' about its pivot 63.

The movement of the link 60 slide designated as awhole by the numera 78and best'seen in Fig. 8 of the drawings. The switching member 78-comprises first a longitudinal body ortion 79, 1 second an arm 80'projecting orwardly from the top manner, as by soldering. The slot 81is so shaped as to permit of the :insertion of the cyindrical lowerportion of" the upperpart of the link- 72in assembling the arts, and

further to permit ,of the vertical p ay within I said slot of theflattened upper end 75, of said link 72 when the latter is recipro- "40cated under the influence of the universal bar during the operation ofthe machine.

In assembling the mechanism the upper flat- 4 tened part 61 of the link60 may be inserted between the sides of the wire loop 82, which lattermay thereafter be riveted 1n thebody l ortion 79 of the switch- 7 8 in amanner best loop 82 under the influence ofthe eccentric faceand saidpart 61 may also.. move up and down transversely of the 100 when the;

, link 60 is reciprocated'by the universal bar.

-87 and at, the lower end in a fork 88 which The longitudinal movementof the jecontric member 64 is controlled by a second switching member 85(F' 2),, which comprises a vertically dispose, arm- 86 terminatmg at thetop in a perforated',collar portion fits into-and embraces the. gXooveor depression 68 in said eccentric member. The collar portion everthesgvitch member 85 -fits' on the inner end of a 1111 and ush rod 8'9and said collar portion is secure thereto b a headed screw 90. .Therod89 extends horizontally beneath the top/plate and termitransversely of,the operating lever 55 and the similar transverse movement of the otherlink 72' are controlled by a switching member or arm 105, the'endwhereof is .natesnearthe right-hand side of the machine in a collar.91 provided with a forwardly extending pin 92,. .The rod 89 issurrounded for the greater part of its length by a sleeve- 93 which is,provided near its left-hand end withaspline 94'. The sleeve 93 has itsbearings in the right-hand bearing lug 47 of the driving shaft ".46 andin a righ-tangled bracket 95' which is secured to the underside ,of thetop plate by headed screws 96. The bracket 95 is slotted to permit ofendwise play of the spline 94 therethrou' h, butthe said spline fits theslot in the racket 9,3

1 with suflicient snugnessto'prevent the sleeve in its'bearin although93 from turnin it-move's freely ongitudinally t erein. The rod .89'moves freely longitudinally'of. the

sleeve '93 which latter serves asa bearing for the said rod. As bestshown in Fig, 4, the collar portion 84 of the switchin "mem ber' 73 fitsover theinner or the 'le ,-h'a nd end of the sleeve 93-and is secured tosaid sleeve by a set'screw 97. The switching. member 7 8-is maintainedconstantly in a horizontal position, by-the spline 94 of the sleeve 93with which latter the member 7 8- issecured in a fixed relation by a setscrew 97. As seen in' Fig. 4, the collar portion 84 of theswitchingmember 78 is positioned between the bracket 95 and the collarportion 87 of the switching member 85.

A collar 98 is fixedly secured to the sleeve 93, between the bracket 95and the bearing v 47 of said sleeve, by a set screw. 99. A; t.

eoileds "rin 100 surrounds the sleeve93 between t e s eeve bearing 47and the collar 98, which latter is'normally pressed by said springagainst .the right-hand face of the bracket 95 thereby positioning thesleeve 93 and the switching member 78 mounted on said sleeve, asindicated in Fig. 4. I

As best seen in Figs. 9 and 4;, the pin'92 at the right hand end of therod '89 is embraced by the fork of a bifurcated crank arm 101, thecollar portion 102 whereof'is fixedly secured to the rear end of ahorizontally dis- .indicated in Fig. 4 When so assembled, p a the part61 may inovelongitudinally of the osed and forwardly extending rockshaft 103. The'horizontal ,portion ofthe .rock

shaft 103 extends through and terminates slightly in front ofthe frontplate 104101? a handle or finger piece 106.

provided with he rock shaft 103 has its bearings in-beari'ng plates 107I and-1108 which are respectively secured to the right hand lug's 42and. 43 by headed screws 109. A collar 110is fixedly secured to the rockshaft 103 and abuts against the .forward face of the rear bearing late108.

' Another collar 111 is fixed y secured in any suitable manner Yto/the"rock shaft and abutsagainst the rear faceof the forward bearing plate107. The collars 110 and 111 serve to prevent endwise motion of the rockshaft 103.

Integral with the collar 111 is a positioningmember 112 which, as'hereinshown, is in the form of a sectoral plate extending to the left anddownwardly from the rock shaft and having its periphery formed withdepressions or notches 113, 114, 115 and 116. A check or locking spring117 is fixedly secured to the under side of the top plate in anysuitable manner and is adapted to en gage the depressions or notches inthe positioning member 112.

The inner side of the crank arm 105 is adapted to cooperate withdifferent faces or stop portions of a sto member 118 which comprises aperforate 01' stops 120; cut-aways or depressions 121 between the hub119 and the side stops 120; and end faces or stops 122 and 123. The

' stop member 118 is fixedly connected, as

by a-driving fit or in any other suitable manner, with a knurledthumbwheel 124 whichis longitudinally perforated to receive a shoulderedscrew 125 which screws through portion of the screw 125, while thethumb, wheel 124'and the stop member 118 rotate: on the shoulderedportion of said screw, being frictionally controlled by an annularcup-like spring plate 131 which is interposed between the rear face ofthe thumb wheel- 124 and the front face of the limiting stop 128, and isshown in detail in Fig. 15.

If the knurled thumb wheel 124 be turned so as to rotate the stop member118 to the position indicated in Figs. 2 and9 and if,

by means of the handle 106, the rock shaft 103 be rotated leftward untilthe crank arm 105 contacts with the side stops 120, as indicated in saidfigures, the positioning memeber 112 will be rotated until itsdepression 11.3 is engaged by the locking spring or check 117 and theswitching members '78 and 85 and'the parts associated with andcontrolled by them will be in the positions in dicated'in Figs. 2 and 4.With the parts so positioned, the ribbon will be fed' longitudinally andwill also be; given a variable crosswise feed so that thef-typeimpressions will make a serpentine or wavy path lengthwise 'of theribbon and extending from side to side thereof. If a ribbon of uniformhub 119 side faces charact er be in place on the machine, a ribbonhaving a plurality of fields of different characteristics may besubstituted therefor in a known manner. A ribbon of the last named kindis represented in the drawings and indicated therein by the numeral 36.

longitudinal stripes or fields a and b and if these be colored, ashitherto suggested, respectively black and red, and the mechanism beallowed to remain in the relations indicated in Figs. 2 and 4, some ofthe type impressions will be printed in black, others in in red, givin avariegated or parti-colored effect which is sometimes desirable inornamental typewriting. Usually, however, it is desired to print all theletters of a word or a succession of words in one color.

Suppose first that it be desired to print in black alone. The handle 106is first swung wheel 124 the stop member 118 is rotated to the right tothe position-indicated in Fig. 10, with the depressed part 121 incontact with the limiting lug 130, and finally the handle 106 is swungto the leftuntil the crank arm 105 contacts with the' end stop 122 when,as indicated in Fig. 10, the depression 114 of the positioning member112 will be engaged by the'locking spring 117. Comparing Fig. 10 withFig. 9 it will be noted that the rock shaft 103 has been rotatedrightward through an are which is represented on the periphery of thesectoral positioning member 112 by the distance between the depressions113 and 114. This rotary movement of the rock shaft causes its rearcrank arm 101, acting on the pin 92, to move the slide rod 89 endwiseand through the sleeve 93 and thereby to draw the eccentric member 64 tothe right to the position indicated .in Fig. 5 with the switch member incontact with the switching member 78. It will be apparent from j aninspect-ion of said figure that the eccentric face has beenwithdrawncompletely from its strap formed by the upper part. 61 of thelink 60 and the forward bent arm 62 from its strap permits the drawspring 77 to swing the link 60 rearwardly about its pivot 63 until thepart 61 contacts with the body portion 79 of the switch member 78, atwhich moment the stud 59 engages the operating lever at the greatestpossible distance from the fulcrum 56 of said lever. If the print-ingdevices be operated with the parts in the relations indicated in Fig. 5,the link 60 acting on the operating lever 55 at the furthest point.possible from the fulcrum 56 of the lever will swing the latter upwardto the least height through which it can be thrown by said link 60during the operation 1 of the machine. With the parts related as The'ribbon 36 is shown as made up of two.

red, and others partly in black and partly to the right, then by meansof the thumb of said link. The separation of the eccentric lastdescribed, this upward movement of the lever is constant and unvaryingand the mechan'ism is so proportioned that the ribbon vibrator is alwaysthrown thereby so as to present the same part of the width of the ribbonto the action of the printing types. The path of the type impressionswill be in a straight line longitudinal of the upper or black field (zof the ribbon.

Sometimes it is desirable. as in preparing stencils for minieographwork, to cause the types to strike directly against the stencil or otherpaper without the interpositioning of the ribbon between them. I haveprovided means to accomplish this result by mechan' ism which preventseither of the links or 72 from actuating the operating lever 55, so thatthe latter will remain quiescent in normal position during the operationof the printing keys. To accomplish this result the handle 106 is swungto the right and the stop member 118 rotated leftward to the positionindicated in Fig. 11 with the depression 121m engagement with thelimiting lug 130, after which the handle 106 is swung leftward until thecrank arm 105 contacts with the end stop 123, which latter is at adistance from its center of rotation slightly greater than is thedistance of the end stop 122 from said center. Consequently the rockshaft 103 is rotated a short distance to the right of the positionindicated in Fig. 10 and the locking spring 117 disengaging from thenotch 11 k engages with the notch 115 in the positicmiug member 112.During this rotary moven'ient of the rock shaft 103, its rear crank arm101 pulls the slide rod 540 still further to the right and the switch1nember 85, which it will be recalled. is

now in contact with the switch member 78. will act on the latter to pullit to the right against the pressure of the coiled spring 100.

the sleeve 93 moving longitudinally with the rod 89 and slidingthronghthe bearings 47 and 95.

of the switch member 78 the upper portion of the link 00 which iscontrolled by the wire loop 82 will be swung transversely of theoperating lever until the stud 59 is disen gaged from said lever, whileat the same time the link 72 is swung to the right until its stud 76stands but a short distance from the operating lever but out ofengagement therewith. there being sufficient spring or give in the twolinks to permit of this movement. transversely of the operating lever.The parts will now be in the positions indicated in Fig. 13, neitherlink being engaged with the operating lever, so that when the printingdevices are actuated. the ribbon vibrator will remain quiescent. innormal position and the ribbon will not be interposed between the typesand the paper.

If it be desired to print only on the red stripe I) of the ribbon, thehandle 100 is During this rightward movement swung rightward until thelast notch or depression 116 of the positioning member e'ngages with thelocking spring 117. the notch 116 and the locking spring 117 being soproportioned and related that the check forms a positive stop for thepositioning member 112 and there is nodanger of overthrow. This furtherrotation of the rock shaft 103 causes the crank arm 101, acting on theslide rod 89, to draw the two switch members 85 and 78 still further tothe right to the position indicated in Fig. 7 thereby increasing thecompression of the spring 100 and bringing the stud 76 into engagement.with the slot 58, and thus operatively connecting the link 72 with theoperating lever The link '72 is guided and controlled by the slot 81 inthe arm 80 so that said link always acts on the operating lever at afixed distance from the fulcrum of the latter. The point at which thelink 7 2 acts on the oper ating lever is nearer the fulcrum of thelatter than is the point at which the link 60 acts on said lever whenthe parts are positioned as indicated in Fig. 5. The result is that thelever 55 has a constant swing under the influence of the link 72 whichis greater than is the constant swing of the lever under the influenceof the link 60, and under the influence of said link 72 the ribbonvibrator is swung to a greater height, the parts being proportioned sothat the lower field or red stripe b of the ribbon will be presented atthe printing point and the path of the types will be in a straight linelongitudinal of said stripe 2)..

From the all red printing position last. explained. the mechanisn'i maybe restored or returned successively into the neutral position indicatedin Fig. 6. the all black positiontFig. 5), or the variegated orparticolored position (Fig. 1). The con'ipresscd spring 100 acts to movethe switch member 78 leftward from the all red position until it hasreached normal position (Fig. .3). while the switch member 85 ispositively actuated through the various return steps to the positionindicated in Fig. l by the slide rod 89. The tapered portion (30 of theeccentric member 64 enables the latter to effect an easy and'certainreengagement with the. strap in the link 60.

.Uthough l have explained and'illustrated the various positions of themechanism in the 'order in which they successively occur. it is to beunderstood that the devices may be operated many order desired. For ex".ample, the handle 100 may be swung from the position indicated in Fig. 0to that indicated in Fig. 12, thereby passing directly from theparti-colored to the all red position, and vice versa; or the shift maybe made from any other position to the desired position as necessity reuircs.

It is further to be um erstood that though I have explained thepreferable mode of using the stop device 118 in commotion with the crankarm 105, yet said'stop device may be manipulated in any other manner asmay be desired. For example, the crank arm 105 may be turned with onehand and simultaneously the stop device may be manipulated with theother hand, or the-stop device may be turned by the thumb wheel.v 1%thereby camming the crank arm 105 from, say, the position indicated inFig. 9 to that in Fig. 10, or from that in Fig. 10 to that'in Fig. 11.Furthermore, if desired, the handle 106 may be manipulated Withoutemploying the stop member 118 at all. The stop member 118 serves both asa stop affording a fixed abutment-for the crank arm 105 and also as anindicating means, being so proportioned that when turned to the variouspositions hitherto described it serves to indicate what section or partof the ribbon will be utilized when the crank arm 105 is broughtinto'contact with said stop member, hence I prefer the latter.

Various changes may be effected in the construction, combination andarrangements of parts, and some parts may be used Without other parts,all without departing from the spirit and scope of my invention.
